JESPER HANSEN, OF WATERBURY, CONNECTICUT, ASSIGNOR TO WATERBURY MFG.CO., 0F WATERBURY, CONNECTICUT, A CORPORATION.

ELECTRIC SOCKET-SHELL AND SHADE-HOLDER.

To all whom it may concern:

Be it known that I, JESPER HANSEN, a subject of the King of Denmark,residing at Vaterbury, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in ElectricSocket-Shells and Shade-Holders; and I do hereby declare the following,when taken in connection with the accompanying draw ings and the lettersof reference marked thereon, to be a full, clear, and exact descrip tionof the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1 a side view of a lamp socket con structed in accordance with myinvention. Fig. 2 a sectional view on the line ab of Fig. 1, on anenlarged scale. Fig. 3 a broken sectional view showing the shade holderengaged with the socket.

This invention relates to an improvement in an electric shell andshade-holder, the object being to provide simple means for firmlysecuring the shade holder to an incandescent lamp socket; and theinvention consists in the construction hereinafter described andparticularly recited in the claim.

In carrying out my invention I employ a shade-holder 2 of desired styleformed with a centrally arranged downwardly turned flange 3corresponding substantially in diameter to the lower end 4 of anincandescent lamp socket 5 of usual construction and which is providedwith the usual annular rib 6 near its lower end. In the lower end of thesocket on opposite sides the metal is struck out to form nibs 7 whichare adapted to engage with the lower edge of the flange 3 of the shadeholder when the shade holder Specification of Letters Patent.

is set over the lower end of the socket. The rib 6 prevents the upwardmovement of the shade holder, and the nibs 7 prevent the downwardmovement. To permit the shade holder to be engaged and disengaged fromthe socket, the socket is formed with a vertieally arranged slit 8adjacent to one of the nibs 7 which permits the metal of the socketabove the nib to be pressed inward out of the plane of the flange of theshade holder.

In applying the shade holder an upward force .of the shade holderagainst the socket will crowd the metal of the socket inwardsufiiciently to permit the shade holder to slip over the nibs; but todisengage the shade holder it will be necessary to slightly press themetal above the nib to force the nib out of the path of the flange whenthe shade holder may be readily removed. /Vhile the shade holder isreadily applied to and removed from the socket, when once engaged it isnot liable to be accidentally disengaged.

I claim The combination with a shade holder formed with a centrallyarranged downwardly extending flange, of a socket formed at its lowerend with outwardly projecting nibs adapted to be engaged with the loweredge of the flange of a shade holder, the socket also formed with avertically arranged slit adjacent to one of said nibs.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.

JESPER HANSEN.
